How Much Will Elvis Presley’s Library Card Bring This Time?

From the New York Times Arts Beat:

Elvis Presley’s earliest known signature – on a library card he signed as a 13-year-old student in Tupelo, Miss. – is one of the main draws in an auction of Elvis memorabilia to be held at Graceland, the singer’s palatial headquarters, in Memphis on Aug. 14.

In 2012, the card was sold for $7500 – a bargain, you would think .
